Another Patent Pool Forms For HEVC
An anonymous reader writes: A new patent pool, dubbed HEVC Advance, has formed for the HEVC video codec. This pool offers separate licensing from the existing MPEG LA HEVC patent pool. In an article for CNET, Stephen Shankland writes, "HEVC Advance promises a 'transparent' licensing process, but so far it isn't sharing details except to say it's got 500 patents it describes as essential for using HEVC, that it plans to unveil its license in the third quarter, and that expected licensors include General Electric, Technicolor, Dolby, Philips and Mitsubishi Electric. The group's statement suggested that some patent holders weren't satisfied with the money they'd make through MPEG LA's license. One of HEVC Advance's goals is 'delivering a balanced business model that supports HEVC commercialization.' ... HEVC Advance and MPEG LA aren't detailing what led to two patent pools, an outcome that undermines MPEG LA's attempt to offer a convenient 'one-stop shop' for companies needing a license." Perhaps this will lead to increased adoption of royalty-free video codecs such as VP9. Monty Montgomery of Xiph has some further commentary.
At least the patents on DVDs are expiring if not already expired. The first DVD player was sold in 1996, and patents can be good for up to 20 years from the filing date, so it would seem that by late next year, all necessary patents should have expired. (Patents are only 17 years from the issue date, so any patents that were actually issued at the time of the first players would have expired.)
I'm sure that they've added on patents for various RW formats, and probably for some new tricks in encoding, but that wouldn't impact playback.
MP3 patents have mostly expired, though one US patent expires later this year.
So for any application using MPEG-2 or MP3, you shouldn't be facing a big patent hurdle. If you want the lower bitrates found with newer codecs, the pain will be with us for a while to come.
Has anybody tried the WebM encoders? They STINK, its either a bunch of CLI gobbledygook or its some half assed support in some other encoder.
If you've talked to anyone on the pirating scene (the ones who actually know what they're doing), controlling x264 through command line is normal. Trying to use a GUI on an encoding test for an anime fansubbing group gets you laughed at.
To answer your question: Yes. Whatever you think of patents (personally I despise software patents and think they're a cancer on our industry), these are not single algorithms, nor are they in any way simple. This is very sophisticated software. At least scan through the Wikipedia entry linked in the summary to get a rough idea of the complexity of these monsters.
Modern video formats are comprised of a vast collection of different algorithms and techniques, and part of the encoding process is determining how best to apply those various techniques to create the best compression while maintaining a specific desired perceptual quality. It's perhaps best to think of a video codec as a family of many different video encoding, decoding, and storage techniques.
Irony: Agile development has too much intertia to be abandoned now.
